Abstract
Fe/Ho multilayers were prepared by electron-beam evaporation. A vector vibrating sample magnetometer is adopted to investigate the multilayers in-plane and out-plane magnetic properties, and an inverted hysteresis loop is obtained in the direction perpendicular to the applied magnetic field. The loop shape is sensitive to the angle between the film plane and the direction of magnetic field. A proposal module is used to explain this mechanism. The results of magnetoresistance measurement show that the multilayers have a positive magnetoresistance. The Fe layer thickness has a marked effect on the electronic resistance and magnetoresistance properties of the Fe/Ho multilayers.
